Error when running library(ggplot2)

Question

Hello I just updated to R 2.11.1 and after installing ggplot2, I tried

library(ggplot2)

and got

Loading required package: proto Loading required package: grid Loading required package: reshape Loading required package: plyr Loading required package: digest Error in eval(expr, envir, enclos) : could not find function "proto" In addition: Warning message: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called 'proto' Error : unable to load R code in package 'ggplot2' Error: package/namespace load failed for 'ggplot2'

Any help appreciated

Peter

Answer 1

install.packages('ggplot2', dep = TRUE) would do the trick... install proto package
